This study was conducted to analyze the factor experiment using a separation simulator and the work performance of each work speed of the 6 row type head feed combine to enhance the harvest performance of the head feed combine. The performance test was conducted by setting it to sieve rotational speed 422 rpm, blower rotational speed 800 rpm referring to the results of the factor experiment. It was confirmed that the working time became shorter as the working speed increased. In addition, when the work speed was 1.5 m/s, the complete grain ratio was high, but there were no significant results for each work speed in terms of the amount of discharging grain loss, the amount of unthreshed grain loss, the ratio of damaged grains, and the ratio of foreign material. It is judged that the separating part did not properly select a large amount of samples in a short time by setting a low rotation speed of the wind port to 800 rpm.
